Designed peptides as functional surfactants (2010–2013)
Surfactants are essential to control of fluid and solid interfaces in applications ranging from drug delivery to the extraction of crude oil. There is strong demand for surfactants with advanced properties such as low toxicity, renewable sourcing, or the ability to respond to changing conditions during use. This work will develop non-toxic, sustainable surfactants that respond to solution conditions to allow stabilization or destabilization of foams and emulsions as required. Outcomes will include advanced peptide design rules, peptides for use at high temperature or with high salt, and specific applications to be developed in close collaboration with industry partners.
